Application tiled May 23, 1884. (No model.)

T0 all whom it may concern:

Be it knownthat I, ROBERT B. PUMPHREY, of the city of Baltimore and State of Maryland, have invented certain Improvements in Meat- Cutters, of which the following is a specification.

This invention relates to certain improvements in that class of meatcutters which are designed to slice or chip dried beef; and it consists in certain details ef construction of the machine, as will hereinafter fully appear.

In the description of my said invention which follows reference is made to the drawings forming a part hereof, and in which- Figure I is a front view of the machine. Fig. 1I is a plan of Fig. I. Figs. III to VIIl, inclusive, are details of the machine on an enlarged scale.

A is a table supported by legs a.

B is the main shaft of the machine, resting in bearings b on the table A. The shaft B is driven from the shaft C, which is revolved through the medium of a crank, c,connecting rod d and a treadle, D, by means of a belt, e, and the pulleys E F.

G is a cutter-head,which consists of the hub f, curved wings g, and the adjustable curved knives h, with their fastening and adjusting devices, hereinafter described.

H. is a hood surrounding the periphery and the rear side of the cutter-head G, and when the machine is in use a front plate, (not shown,) having a hole large enough to admit the piece vof meat to be chipped, is secured over its front or open side.

I is a metal plate, upon which the piece of meat to be cut is placed, and its inner edge, z', forms the stationary member of the cutter, and is nearly in contact with the knives h as they revolve.

J is a spring-holder for the meat, andit consists of a spring-wire,j,fastened to the post k, and a roller, Z, adapted to revolve on the free end of the wire, which is bent at a right angle to receive it. A

K is a square bar, which passes through a bracket, m, having a thumb-screw, a, to hold the bar in any position within range of its movement.

L is a plate fastened to the inner end of the bar K, against which the meat to be chipped rests. By means of this adjustable plate any sized piece of meat may be guided to the cutters when fed thereto by mechanism hereinafter described.

M is a feed-screw, with a saw-tooth thread,

which is held in bearing-boxes o and revolved from the shaft C through the medium of a belt, p, and a pair of cone-pulleys, N. By shifting the belt on the cone-pulleys the speed of the revolving screw may be increased or decreased.

O is a carrier for the meat, and it is formed of a slotted arm, q, with prongs r fastened thereto by means of a bolt, s, which rests in the slot t.

The carrying-arm q is fastened to a sleeve, P, having an internal diameter larger than the outside of the thread of the screw M.. A portion of the sleeve P is cut away, and a halfnut, Q, inserted in the opening. This halfnut is hinged to the sleeve P, and provided with a spring, a, to withdraw it from contact with thev thread of the screw M. (See Fig. III.) The half-nut Q, when the'carrier O is to be put in operation to feed the meat to the cutter-head, is held down by means of a button, o, having a lever, w, which is lapped over a projection, x, of the half-nut Q.

The button is automatically disengaged from the half-nut, and the same allowed to spring upward and from contact with the thread of the screw M before the carrier strikes the knives by means of a pin, R, projecting from the table A.

Avery nice facial adjustment of the knives h is obtained by means of the wedges S, which are situated between the rear sides of the knives and the cutter-head arms g, and the screws T, which turn loosely in a slotted projection, y, of the wedges, and are screwed into the said arms. The wedges arealso slotted to allow of -their movement without affecting the screws z,

which hold the knives, and are set up after the same are adjusted.

I claim as my inventionl. In a machine for chipping dried meats, the cutter-head G,having the curved wings g, and curved knives h,secured to the said wings by means of screws z, combined with the wedges S,interposed between the said knives and the wings of the cutter-head and slotted to fit IOO the cutterdiead G,havin g k nives,substantially as described, in combination with the plate I7 feed-screw M, devices for holding the meat adapted to be forced to the cutters from the said feed-serew, the bracket m, set-sereW-n, and bar K with the plate L,whereby the'meat is guided to the said cutting-head during the feeding Operation, substantially as specified.

ROBERT B. PUMPHREY.
